Application filed January 28, 1882. (No model To all whom it may concern Be it known that LFRANK ALEXANDER GRUNOW, aresident ot' the city of New Orleans,

'This invention relates to that class of machines which are more particularly intended.

for purposes of irrigation and drainage; and it consists in a peculiarly-constructed pump or elevator, through the instrumentality of which large quantities of water may be raised within a given time.

In order that the nature of my invention may be fully understood, reference must be had to the accompanying drawings, whereon the same is represented on two sheets.

Figure l is a horizontal section of the operating part of the machine Fig. 2, a vertical cross-section of the'whole arrangement, and Figs. 3 and 4 details thereof. Fig. 5 is a 1ongitudinal section through the elevator, and rlsothrough the frame in which itis mounted, showing oneof the uses to which said elevator may be applied.

as shown at Fig. 5, Sheet 2.

On the drawings, the letter A represents the lower section of the machine. This part is cylindrical in form, with a supporting-Hange, b, by which it is secured in position and upon which is bolted the wheel-chamber, the latter consisting of an annular ring, e, having four vertical hollow columns, f, that serve to sup port the cover or cap D and thevweight of the columnof water resting upon the same when the machine is in operation.

The upper ends of the hollow columns are provided with anges y, or, if preferred, with an annular ring corresponding with that at their lower ends. Upon these lianges or ring is bolted a dome-shaped cover, D, having a central vertical hole and stuffing-boga', for the reception of the main shaft k, and with similar holes and stuftlng=boxes, l,in the lugs l ,for the passage of the elevating-rods m, the lower ends of which are threaded and fitted into the outer ends of a cross-piece, N, the center of which is furnished with a'step, o, upon which rests the lower end of the main shaft lc.

For the support of the cross-piece the bottom of the lower section is providedwith four inner projections or seats, @which are strengthened on the inner side of the cylinder by ribs g and i", the upper portions of the lattercut away, a-s at s, to form passages through which the outer ends of the cross-piece may be passed into position. Between the aforesaid seats are open spaces,, for the free admission of water.

Within the wheel-chamber, andkeyed or otherwise secured to the main shaft, is a Wheel composed of a solid circular plate, C, the upper surface of which is of the same configuration as that of the cover D, while Ythe inner surface follows the line thereof until nearing the center, where it curves downward into a solid boss, as at t. From this plate C vertical knives B project downward, and are connected at their lower outer ends by an annular ring, u, which travels in a groove, c, thatis made on the upper surface of the lower section, A. The above knives 'are set at an angle about ninety degrees, and rotate in the direction'shown by the arrow in Fig. 1.

The apparatus, as above described, is fitted Vin a circular, square, or other shaped casing,

in which the water is raised and projected through a trough or gate.

The action ofthe pumpis as follows: The water enters at the bottom of the casing through suitable grating, (so as to prevent accidents by the suction of floating material.) and is cut or shaved and thrown outward with such force as to cause the same to rise to a sufficient height to be expelled from the casing orto be carried still higher by a second pump placed immediately above the other. The peculiar shape of the top of runnin g-wheel causes the same to be slightly raised as the water is being expelled, and the dome or cover, following the same curves, leaves avacuum-space between the two, thus reducing the frictionsurface to that end of the shaft which rests upon the step O.

The running-wheel is adjusted at its proper height bymeans of the elevatin g-screwsm, the lower ends of which operate against the seats 15;

In Fig. 5 is represented one plan of utilizing loe my elevator. It consists of a frame-Work constructed in the pond or place to be drained, the said frame having one of its ends, E, open for the admission of the water, which passes Having described my 1nvcntion,\vhat Ielaim as new, and desire to secure by Letters Patent, is-

ll. In a water-elevator, a wheel haring a solid top, C, and bottom ring, u, in combination with the angular knives connected to and supported by said top and ring, substantially as and for the purpose set forth.

2. In a water-elevator, the cylindrical section A, provided with seats p and ribs q r, to receive the outer ends of the cross-piece N, as described, and for the purpose set forth.

3. In combination with the running-wheel, eomposedof top C, knives B, and annular ring u, the shaft k, cover D, lower section, A, elevating-screws m, and cross-piece N, alleenstructed and arranged to operate within a cas ing, i'or the purpose described.

ln testimony whereof I hereunto sign my name.
